The present study was conducted to investigate the allelopathic effects of aqueous and ethanolic common 10 weed (Alternanthera sessilis (L.) R.Br,ex DC, Amaranthus tricolor L., Cardiospermum helicacabum L., Corchorus olitorius L., Cyperus rotundus L., Euphorbia heterophylla L., Euphorbia hirta L., Phyllanthus amerus Schumach. & Thonn. , Portulaca oleracea L., Vicoa indica (L.) DC.) extracts on Seed health (incidence of seed mycoflora, seed germination and seedling emergence, root and shoot length) of Wheat var. local under laboratory conditions. The result observed that the aqueous leaf extract of Euphorbia hirta L. showed highly reduced seed mycoflora and stimulatory for seed germination, seedling emergence, root length and shoot length as compared to the other weed plant extract and control. It is followed by Portulaca oleracea L. (root, stem and leaf extracts). The medium effect observed in extract of Alternanthera sessilis (L.) R.Br,ex DC and mínimum result were observad in both root extracts of Cyperus rotundus L. The aqueous root, stem and leaf extracts of Amaranthus tricolor L. and Cardiospermum helicacabum L. showed bad effect on seed health. The result is demonstrated the allelopathic potential of ten common weeds in same wheat field and suggested that those weeds may affect wheat seed health due to inhibitory or stimulatory effect of allelochemicals which are present in the extract of weeds.
